To all whom t may concer/ri.'`

Be' it known that I, HERBERT lil-mmany .KEELER, a citizen of the United States, re-

siding at Chicago, in the county of Cook and tate of Illinois, have invented fa certain new and useful Improvement in Ice Ficks, of which the following is a specification.

My invention relates to ice picks, more articularly of the type in which the handle 1s slidably mounted upon a pointed rod for imparting a blow to it, and a helical spring is interposed between the parts to normally hold the vrod in projected position; 'In previous constructions the parts have been so designed that the inner end ofthe rod was apt to become; fouled by the ,turnsI of the spring, thus causing the parts tojam and preventing proper operation. The object ofiny invention is to .provide 'simple-andeiiicient means for preventing such pondltion. Another object of the invention is to provide a simple and inexpensive form of assembly so that the parts may be readily produced on Ordinar machinery andV readily @assembled after tie individual parts have been-produced. v

I .obtain my objects by the mechanism illustrated in theaccompanying drawings in which- Figures 1 and 2 are assembly viewschieiy l in diametral'section showing the parts' in ydifferent relative positions A Figure 3 is'a top plan vlewof yFigure Figure 4 is a distributive view showing the relation of the pointed rod to the supporting sleeve. p j

Figure 5 is an assembly view chiefify in diametral section showing a vmodified orm of the device.

Figure Gis an assembly viewV chiefly indiai'netral section showing still another modification infwhich the rod is introduced from the lower end of the handle.

Fi rure 7 is a bottom plan section on the line 7 Figure 6.

Like numerals denote like parts throughout the several views.

. Referring first to the type of device shown in Figures 1 to 4 inclusive, a' rod 1 is pointedv at the outer end for acting upon the ice. .At a location somewhat below the upper end of the rod there is a collar 2 which by preference is integral with the rod'. This collar forms an abutment for the lower end of a helical compression/spring 4 which each blow is struck n turn the parts to the original position. vThe encircles the upper end of the rod and' is containedwithin the hollow stem of the handle 6i In this type the lower end of the handle is closed so as to form a stop for the collar 2 although it is apertured to accommodateand guide the rod beneath the collar. By preference the handle has a weighted head 8 which is not only` convenient to Ibe grasped by the user but adds weight to the moving parts so as to increase the force of the blow delivered to the upper end of the pointed rod when in action. In order to prevent the tool from rolling when laid on the table or other surface it is desirable that the .head have a flattened side V9 as illustrated in Figure 3.

According tothe 'design shown in Figures i 1 to 4 the upper end of the handle is closed by screw plug 1() whichforms an abutment 'for the upper end of a tube or sleeve 12 which is spaced far enough from the inner walls of the handle to accommodate the presence of .the upper end of the spring and illustrated in, Figure 1. The rod is 4freely slidable withinthe tube andthe lower end of the tube is "preferably bevelled to insure non-interference with the spring. y l

In operation, the parts normally assume the position shown in Fi re 1. In cracking' ice the operator places t ev point of the rod at thelocation desired and then impart-s a series of sharp blows by rapidly moving the handle a number of times down upon the rod fl so that the upper end thereof is'engaged by 10 as illustrated in Figure 2. Afterl the lu p g the spring 4'tend's to retube 12 connes'the spring to its proper location and prevents it from buckling or in interfering with the free movement 100 any wise of the r'od. In other' words, the tube cone stitutes means for holding the spring in alinement and for separating thel upper end of the rod at all times from the spring.

The type shown in Figure 5 is analogous to the type hereinabove/described but in this case the spring 14 does not extend substantially throughout the length of the handle'- but abuts the lower end of atube or thimble2 15 which occupies the' entire 'cylindria l as in the previous one,f'the tubular member space betweenthe rod and inner wall offtlieano handle. It will be evident that inthis'forn, y

always protects the upper end of the rod l and prevents it from coming into engagement with the spring.

.In Figures 6 and 7 I have shown still another type which is constructed similarly to the type shown in Figures l to 4 except that in lieu of the plug 10 the head 18 of the handle is solid and the lower end of the hanene instead ef being integral is closed b e screw plug 20 controlled by a nut 21. 'Izhe plug is of sufcient diameter to permit all of the parts within the handle to be withdrawn through the opening which the plug closes. One advantage' in this type is that the rod strikes an integral portion of the handle instead of striking a part which is simply screwed thereinto.

It will be observed that in all of these various types of construction there is a tubular element which at all times prevents the inner end of the rod from coming into contact with the spring, thus avoiding any possibility of the rod becoming caught in the spring.

Also the spring itself is always held in alinement and loosely confined to the position it ought to occupy. It is evident that the size andshape of the head on the handle may be greatly varied w-ithout departing from the spirit of the invention.

Having thus described my invention, what I claim as new and desire to securevv by Letters Patent is:

l. An ice pick having a pointed rod, a handle slidably mounted on the rod, a helical spring surrounding the rod Within the handle, and a tubular element within the handle and encircling the rod, said tubular element being adapted to engage the spring and keep the turns thereof out of contact with the inner end of the rod.

2. An ice pick having a pointed rod with a collar fixed upon it between its ends, a hollow handle slidably mounted 'upon the rod and enclosing the upper end thereof, the lowerend of the han'dle being apertured to accommodatethe rod, and being otherwise closed to form a stop adapted to be engaged by the collar to limit the outward movement of the rod, a helical spring resting at one end upon the upper surface of the collar and at the other end abutting the inner end of the handle, and a tubular element within the handle interposed between the spring and the rod for preventing the upper end of the rod from jamming against the turns of the spring.

3. An ice pick having a hollow handle, a pointed rod slidably mounted within the handle, means for "limiting the outward movement of the rod, a helical spring enclosed within the handle, the spring abutting the rod at one end and the handle at the other for urging the rod outward, and a tube forming a lining for the upper portion of the spring, said tube extending downward far enough to cover the upper end of the rod when the latter is projected outward the maximum distance.

4. An ice pick having a hollow handle which is solid atl its upper end, a pointed rod slidably mounted within the handle, a collar rigidly mounted on the rod between the ends, a helical spring enclosed within the handle and adapted to urge the rod outward, and a screw plug closing the lower end of the handle. said plug being apertured to guide the rod and being adapted to limit the outward movement of the collar.

In witness whereof, I have hereunto subscribed my name.
